I agree. In every other tree shown it has been 1/2 or more of the tree that was lame, the entire smithing tree is lame. Every single one of those perks should just be part of raising your skill. So if you have a 100 in smithing what all you can do is leather or iron or something? That is just a dumb system it almost totally negates the point of leveling a skill if you need to take perks to make it functional. You aren't getting a new cool ability, nothing to make you specialize your character, you are gaining the ability to be a smith which kind of been covered by you raising the skill to 100.
Please see my above post, and to add...what was the big thrill with attributes? Standing in the wilderness spamming heal spell to level my restoration was sooo much fun? Jumping in place over and over? Swinging a sword at 100 mudcrabs just to get some points? And then what- well now I'm strong enough to play the game. Yay...
Sure, smithing may not seem overwhelming, but we don't know what the other perks are yet. As I mention above, the shield/block tree has an actual learned skill you wouldn't otherwise get from just levelling block, so we WILL be getting exclusive skills through the tree, opening up the game for more replay value.
As far as your kinda ridiculous anology goes, I'll bite...I drive every day. I have for years, I do it over and over again. In a previous TES game, that would skill up my Driving, giving me access to motorcycles, boats, 18 wheelers, even though I haven't trained in their use at all. Perks make more sense- it's like going to a special skills trainer who teaches you HOW you can use those 100 points, instead of just mindlessly skilling them up.
